Weird Sync Sound Problem!!!

Hi,
I'm having this really annoying problem. At my school I captured a ton of footage from DV on a few different decks over a few different days.
Half of the footage goes out of sync when I play it in FCP (6.0.1). When I open those files in QT they are fine, but in FCP they are out of sync. So I looked in my Browser to see what could be different about the clips that are fine and the clips that go out of sync. Turns out that the out of sync clips were captured on two specific days, and the working ones were on different days. Also, under the "audio" column, the out-of-sync ones say they are 2 mono tracks, as opposed to the 1 stereo for the working ones.
Remember, there is no problem at all opening these in QT. Weird!

I'm assuming there was some incorrect capture setting on the days I captured the out-of-sync clips, but I'd hate to have to recapture ours of footage.
I've tried going into Sequence Settings to fix it but haven't found something that works.
Somebody please help.
thanks,

the audio was recorded the same way on the clips that work and the ones that don't. they must have been captured differently though if the bad ones are 2 mono and the good ones are 1 stereo. The audio says 48.0 and 16-bit for all clips.
But even if they were 32 Kb, why would I not see a sync problem when opening in QT, but have a problem in FCP with the same exact clip?
Some weird bug?

If the clips play fine in the quicktime player, but not it FCP then it's probably that you are playing the video out firewire and audio out somewhere else? This happened to me. I had the audio going out my soundcard and video out on the firewire to external monitor. The audio was way out of sync, but by setting "audio follows video" it fixed it.
 
ok, i went there and was not able to change it to "audio follows video" because that option is gray. It was set to Firewire DV, I switched it to Default and it didn't change anything.

also, remember that it some clips in the same project are perfectly fine (the ones listed as 1 stereo track, instead of 2 mono), so it would appear to be something with specific clips, not with the general set up of my FCP project.
